CINCINNATI — The Bengals activated defensive tackle Geno Atkins from the Physically Unable to Perform list yesterday after missing seven games last season because of a torn knee ligament.

“He has developed into one of the better pass-rushing interior lineman in this league,” coach Marvin Lewis said. “Him coming back gives us a huge strength.”

Lewis said the Bengals had players step up well in place of Atkins, and the experience helps the team’s depth heading into the season.

Guard Clint Boling, however, was less enthused about the news. He practices against Atkins.

“I’m probably the only guy in the building that is disappointed he’s back,” Boling said.

Cornerback suspended

Cornerback Chris Lewis-Harris was suspended two games for violating the NFL substance-abuse policy, a league spokesperson said. The cornerback can continue to practice and play in exhibition games, but he will not be eligible for the active roster until Sept. 15. Lewis-Harris played six games last season and registered four tackles on special teams.

Offense takes shape

Coordinator Hue Jackson’s new offense, a more up-tempo style of play compared with recent seasons, has quarterback Andy Dalton and new starting running back Giovani Bernard excited.

“We’re very comfortable with the new system,” Dalton said. “A lot of us have grown with this team together, and it makes the adjustments easier.”

Bernard said he’s looking forward to being used in a variety of ways.

“I think that is why they drafted me, but this offense is going to allow me to show what I can do,” Bernard said. “You never really know what Hue is going to do.”

Wrapping up

Rookie linebacker Marquis Flowers was activated from the PUP list. … Offensive tackle Andre Smith, linebackers J.K. Schaffer and Jayson DiManche and tight end Kevin Brock are under the NFL concussion protocol as of yesterday.
